    摘要： The present invention provides a method of regenerating a carbon dioxide absorbent which absorbs carbon dioxide emitted from various anthropogenic sources including fossil fuel combustion processes, industrial production processes, and natural gas processing. In the method, the absorbent is preheated using heat generated in a process of compressing the separated carbon dioxide in a compressor and the preheated absorbent is delivered to an absorbent flow control tank, before the used absorbent is delivered to a regeneration tower, thereby improving energy efficiency.

    摘要： Disclosed is a method for solidifying carbon dioxide into carbonate, in which carbon dioxide is stably converted into and solidified into carbonate (mineral facies) by using steel slag or natural mineral by extracting an alkali component by supplying an ammonium salt solvent as an extraction solvent to raw slag and injecting carbon dioxide into an extract solution supplied to a carbonation reactor to produce carbonate precipitate from the extract solution through the induction of a conversion reaction of the carbon dioxide into the carbonate precipitate. Then after the above two step are performed at least one an acetic acid solvent is supplied as an extraction solvent to the raw slag so as to finally extract an alkali component; and carbon dioxide is injected into an extract solution to produce carbonate precipitate from the extract solution through the induction of a conversion reaction of the carbon dioxide into the carbonate precipitate.

    摘要： The present invention relates to a carbon dioxide absorbent. In particular, the present invention relates to a carbon dioxide absorbent comprising an ionic liquid, amine and glycol. Since the carbon dioxide absorbent of the present invention can retain excellent CO2 absorption capacity despite repetitive regenerations at low temperature, it can reduce energy consumption and a loss of absorbents used, and therefore, can be effectively used for a process of collecting carbon dioxide from exhaust gas and natural gas and separating the same.
